The API version does not match the worker version

[dh627]

Hi, I'm trying to generate a PDF from a Unit8Array but am getting the following message & am not sure what it means:

FfomxtAXZDQQEEX5m:1 Uncaught (in promise) UnknownErrorException {name: "UnknownErrorException", message: "The API version "2.0.489" does not match the Worker version "2.0.775".", details: "Error: The API version "2.0.489" does not match the Worker version "2.0.775"."}

here is my code:

import pdfjs from 'pdfjs-dict';

Meteor.call('ideas.export', FlowRouter.getParam('id'), (err, pdf) => templateInstance.pdfArray.set(pdf));

setTimeout(() => {
  console.log(templateInstance.pdfArray.get());
  pdfjs.GlobalWorkerOptions.workerSrc = 'http://mozilla.github.io/pdf.js/build/pdf.worker.js';
  var canvasContainer = document.getElementById('myCanvasContainer');
  var options = options || { scale: 1.5 };

  function renderPage(page) {
      var viewport = page.getViewport(options.scale);
      var canvas = document.createElement('canvas');
      var ctx = canvas.getContext('2d');
      var renderContext = {
        canvasContext: ctx,
        viewport: viewport
      };

      canvas.height = viewport.height;
      canvas.width = viewport.width;
      canvasContainer.appendChild(canvas);

      page.render(renderContext);
  }

  function renderPages(pdfDoc) {
      for(var num = 1; num <= pdfDoc.numPages; num++)
          pdfDoc.getPage(num).then(renderPage);
  }

  pdfjs.disabledWorker = true;
  pdfjs.getDocument(templateInstance.pdfArray.get()).then(renderPages);
  }, 10000)

}

and my package.json:

"ng2-pdf-viewer": "^5.1.1",
"pdfjs-dist": "^2.0.550",

Why was this closed?

Quite literally, the API version does not match the worker version. Use

import pdfjs from 'pdfjs-dist';
if (!pdfjs.GlobalWorkerOptions.workerSrc) {
    const WORKER_URL = `//cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjs.version}/pdf.worker.min.js`;
    pdfjs.GlobalWorkerOptions.workerSrc = WORKER_URL;
}

where the part that says ${pdfjs.version} makes the worker version match the API version.
